' PLANER FEED-ROLL.-

SPECIFICATION forming part of Letters Patent No.3l1,063, dated January 20, 1885. Application tiled December 1984. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN CONNELL, of Rochester, county of Monroe, State of New York, have invented Improvements in Planing-Machines,of which the following isa specification, reference being had to the accompajecting studs passing through openings in the nying drawings.

My present invention relates to certain improvements in planing-machines, which improvements are fully described in the following specification and the novel features thereof specified in the annexed claims.

In the accompanying drawings, Figure l is a transverse section of a planing-machine embodying my improvements. Fig. 2 is a side elevation. Fig. 3 is a plan view. Fig. 4 represents the box at the end of the upper feedrolls. Fig. 5 represents the expansion-gearing. Fig. 6 is avertical section on the line as m. Fig. 7 is a horizontal section on the line y y of Fig. 6.

In the accompanying drawings, A A represent the side frames of a planing-machine of any ordinary construction, to which my present improvements are to be applied. B is the upper feed-roll, and B the lower feed-roll.

0 represents the stuff to be planed passing between the feed-rolls.

The lower feed-roll, B, revolves in suitable journal-boxes on the side frame, and is driven by power in any ordinary manner. The upper feed-roll, B, is driven from the lower feedroll by means of the train of expansion-gearing 9 9, provided with links M, Figs. 1 and 5, or in any other preferred manner. The upper feed-roll, B, is provided with the journals 0 0, which revolve in the journal-boxes r r. The journal-boxes r r are arranged to slide up and down on standards 9 g, secured to the side frames of the machine. The journal-boxes are provided with projecting lips or gibs Z, which reach over the edge of the standard 9 g and secure the boxes thereon while moving upand down. (So represented in Fig. 4.) The inner face of the lip l is slightly curved or rounded where it bears on the edge of the standard, so as to permit one end of the feedroll to rise independently of the other end, as indicated by dotted lines in Fig. 4. The up per feed-roll, B, is held down to its work by the weights J J on the levers I I, which are pivoted to the side frames at n, and connected with the journal-boxes r r by means of screws or threaded rods 0 c. The side frames are provided with suitable stops, t, arranged to limit the downward motion of the levers I I. At their lower ends the screws 0 c are inserted in the nuts d, which are provided with prolevers. These studs may be either provided with nuts inside the levers, as represented at a, Fig. 1, or they may be threaded and inserted in threaded holes in the levers. At their upper ends the screws 0 c are connected together by the bevel-gears L and the shaft N, by turning which the upper feed-roll, B, may be raised and lowered parallel with the bed of the machine, so as to adapt the machine to planinglumber of different thicknesses. Shaft N is supported in suitable bearings attached to the journal-boxes r 'r at their upper ends, and below the bevels L the screws 0 0 pass through bearings or collars e e, which are pivoted to the journal-boxes by means of studs 8 8. These studs may be threaded and inserted into threaded holes in the j ournal-boxes; or, as represented in Figs. 6 and 7, the studs s may be provided with nuts located in recesses in the journal-boxes. Collars o are attached to the screws 0 cbelow the bearings e e.

The operation of my invention may be readily understood from the foregoing descriptions and an inspection of the drawings.

In Fig. 1 I have indicated by dotted lines the position of the parts when one end of the upper feed-roll rises independently of the other end to accommodate itself to an irregularity in the lumber passing through the machine.

In Fig. 2 I have indicated by dotted lines I the position of the parts when the upper feedroll is raised by lumber of unusual thickness. The links t z are fitted loosely in their bearings, so as to permit the independent movement of either end of the upper feed-roll.

My present invention presents great advantages over any device which has been hitherto in use for accomplishing the same purpose, in that it is cheaper to construct,

works with less friction, is more durable in operation, and permits of the adjustment of the upper feed-roll to different thicknesses of lumber with greater facility and less loss of time.

ICO

I clairn 1. The combination, with the upper adjustable feed-ro11 of a planing-machine, of the screws 0 c, pivoted to the journal-boxes of the feed-roll, and threaded directly into the pivoted nuts d d, attached to the weighted levers I I, substantially as described.

2. The combination, with the upper adjustable feed-roll of a planing-machine, of the screws 0 c, pivoted to the journal-boxes of the feed-r011, and threaded directly into the pivoted nuts d d, and provided at their upper ends with bevel-gears L L and connectingshaft N, substantially as described.

3. The combination, with the journal-box I 5 'r of the upper adjustable feed-roll of a planing-machine, of the screw 0, pivotally connected with the journal-box by means of the collar 6, provided with stud s, substantially as described.
